Abstract
Disclosed is a viscous coupling that has a housing that carries ribs that are arranged concentrically about a central axis. A rotor is provided that can rotate relative to the housing about the central axis in a predetermined direction. The rotor also carries ribs, and the ribs of the housing and the rotor are arranged in a working chamber surrounded by the housing. Also provided is a fluid reservoir. A fluid discharge line leads from the working chamber to the fluid reservoir. A wiper is moveably arranged between the housing and the rotor and scrapes fluid from the rotor and feeds it to the fluid discharge line. A stop is provided for the wiper and is arranged next to the rotor.
